The application just can comprise the system of multiple equipment, assembly, module etc. to provide various scheme or feature.Be understood that and understand, each system can also comprise additional equipment, assembly, module etc. and/or can not comprise all devices, assembly, module etc. discussed by reference to the accompanying drawings.In addition, the combination of these modes can also be used.

With reference to figure 1, what illustrate is wireless communication system 100, and it contributes to distributing a part for one or more Resource Block for ul transmissions to equipment.System 100 comprises (such as, to be provided to the access of the wireless network) base station 102 communicated with equipment 104.Base station 102 can be macrocell, Femto cell, picocell or similar base station, via node, mobile base station, the equipment communicated with equity or self-organizing mode or their part, like this.Equipment 104 can be UE, modulator-demodulator (or other band cable equipment), their part, like this.Such as, equipment 104 can connect with base station 102 (such as, by Stochastic accessing or similar program) and can receive Resourse Distribute from base station 102 for its transmission signal.

Such as, this Resourse Distribute can relate to a part for time on the data channel (the physical uplink link shared channels (PUSCH) such as, in LTE) shared between multiple equipment that can communicate in base station 102 and frequency resource.In LTE, such as, at least one Resource Block at least one TTI can be distributed to send signal to base station to each equipment in base station 102.TTI can be the subframe of crossing over a millisecond (ms) in time domain, and a radio frames can comprise 10 subframes, and therefore a radio frames can cross over 10ms.In addition, each TTI or subframe can have the time slot of two 0.5ms, depend on the Cyclic Prefix that base station 102 utilizes, and each time slot comprises 6 or 7 data symbols (such as, SC-FDMA symbol).In addition, base station 102 can allow 8ms between the Resourse Distribute for equipment 104, to send feedback to equipment 104.Therefore, in many configurations, and every 8 subframes (such as, or 8ms) distribute a Resource Block to equipment 104, send to base station 102 on PUSCH.Further, in a frequency domain, Resource Block can comprise the multiple subcarriers on the data symbol of time slot or subframe.Such as, Resource Block can comprise in time slot or subframe data symbol on the set of 12 subcarriers.In addition, each subcarrier can comprise the frequency bandwidth of 15 KHz (kHz) substantially, thus Resource Block can comprise 180kHz.

When equipment 104 power limited, it possibly cannot utilize whole Resource Block to send.Therefore, the part (the one or more subcarriers such as, in Resource Block) of the Resource Block in one or more TTI can be distributed and equipment 104 can send on the portion in base station 102.As shown in the figure, equipment 104 can send signal to base station 102 in radio frames 106.As described herein, radio frames 106 can comprise 10 Resource Block on 10 TTI108.The frequency-portions (such as, a part for subcarrier) of the Resource Block on the TTI110 of binding can be distributed in base station 102 to equipment 104, and equipment can send signal during the TTI110 of this binding in this Resource Block part.Like this, equipment 104 sends in a period of time in limited bandwidth.Base station 102 can distribute the other parts of the Resource Block during the TTI of this binding similarly to other power constrained devices, to optimize distributed bandwidth.

Therefore, for the application (as based on the voice (VoIP) of Internet Protocol or other stream application) of time-sensitive, equipment 104 can use less frequency-portions but send signal to base station 102 on the TTI of multiple binding due to Power Limitation, thus effectively communicates with higher data rate.In an example, be appreciated that, because power constrained devices can not use the whole bandwidth of Resource Block, can be more more useful than of distributing in four full resource blocks to each power constrained devices so allow 4 power constrained devices to carry out transmission during the TTI of 4 bindings in the different part of same Resource Block.

Forward Fig. 2 to, show the example wireless communications 200 contributed to one or more power constrained devices Resources allocation.System 200 comprises the base station 202 of wirelessly communicate with equipment 204 (such as, so that the wireless network being provided to it accesses).Base station 202 can be equipment, their part etc. of macrocell, Femto cell, picocell or similar base station, via node, mobile base station, equity or self-organizing mode, and equipment 204 can be UE, modulator-demodulator or their part etc.Further, base station 202 can comprise: selectable power constrained devices determination assembly 206, for determining whether the one or more equipment communicated with base station 202 are power limiteds; Resourse Distribute determination assembly 208, for selecting a part of resource to distribute to described one or more equipment; And Resourse Distribute assembly 210, for transmitting this Resourse Distribute to described one or more equipment.Equipment 204 can comprise: Resourse Distribute receiving unit 212, for obtaining Resourse Distribute from base station; Emitting module 214, communicates with base station for passing through distributed resource; And selectable feedback reception assembly 216, it obtains the feedback relevant with the communication distributed resource from base station.

According to an example, Resourse Distribute determination assembly 208 can determine based on one or more aspects of equipment 204 or miscellaneous equipment the resource will distributing to equipment 204 at least in part.In an example, power constrained devices determination assembly 206 can determine whether equipment 204 is power limiteds.This can comprise, and such as, from the instruction of equipment 204 received power restriction, receives instruction from network or one or more miscellaneous equipment (not shown), like this.In another example, power constrained devices determination assembly 206 can at least in part based on according to determining that equipment 204 is power limiteds with the one or more characteristics (as signal strength signal intensity etc.) measured by the communication of equipment 204 before.When equipment 204 power limited determined by power constrained devices determination assembly 206, or on the contrary, the distribution that Resourse Distribute determination assembly 208 can determine equipment 204 comprises a part for the Resource Block on the TTI of one or more binding.In an example, Resourse Distribute determination assembly 208 at least in part based on the degree that this plant capacity is limited, can determine the size of this Resource Block part.Such as, this can comprise determines that equipment can carry out the maximum quantity of the subcarrier sent thereon in the given time period, and distributes the part of this Resource Block according to this number of subcarriers.In any case, as described herein, Resourse Distribute determination assembly 208 can also determine the distribution in the other parts of the Resource Block gone up at least partially of the TTI in this one or more binding for miscellaneous equipment.
